Indoor carpet off-road racing is a growing segment of the RC racing scene and Pro-Line is ready to take over with their new Pin Point SC and 4wd Buggy tires. The Pro-Line Pin Points have tons of ultra-sharp pins in a unique sine wave pattern that grip the carpet better than Velcro. Pro-Line engineers have perfected an all-new carpet tire compound (Z3) specifically for the needs of indoor carpet racing. This new Z material provides the best grip on a variety of surfaces used indoors.
